A vision this large cannot move forward without buy-in from key executives, and it is unlikely for the execution to take 9-months. Therefore, like other comments have postulated, the work had to have begun long before Nadella took over as CEO. Let's say, for the sake of argument, that this announcement was made under Ballmer. How many of you would trust this announcement/take it at face value? Even going by this thread, there is a deep distrust of Microsoft's moves, and that is despite all the positive press that Satya has received for creating a more "open" Microsoft. IMO, the biggest change that Satya's moves have resulted in is a change in the "perception" of Microsoft's intentions. The non-Microsoft community trusts his intentions, and by association his actions, more than they did Ballmer's. I don't blame this lack of trust, heck I subscribe to it. But attributing all of these decisions to just Satya shows a lack of appreciation for how decisions of this magnitude are made at a company like Microsoft.
